Do not hold me to my words avi forexample I can do animations off asf I cannot

avi may be a tab bigger, and asf more compressed. I can never get it right asf is newer so when you record your movies on a dvd it will be formatted dv-avi. so like i said you may wantto research your question until another member has the right answer sorry Mod FISHY

This is a very good question, and one that I've seen no professional opinions about. Does asf or avi permit higher quality? One thing I know for sure is that there is more video post-processing software available for avi than asf. But asf files are about 15% larger.

This becomes a bigger problem when you purchase newer hybrids and the videos from your old one won't play on the new one.
